The polyolefin film has an Average Hole Count between about 0.0 and about 10.0, according to the Gel Count Test Method. The polyolefin film has an Average Gel Count between about 0.0 and about 100.0, according to the Gel Count Test Method. The polyolefin film has an Average Relative Gel Height between about 0.0% and about 150.0%. The polyolefin film has a Total Spot Count between about 0.0 and about 100.0, according to the Gel Count Test Method.

FIELD

The present disclosure is generally directed to polyolefin filmscontaining recycled polyolefin materials and having acceptablemechanical, visual, tactile, and/or chemical properties.

BACKGROUND

Consumer products are often packaged and sold at retail in soft packagesformed of plastic polymer film. Plastic film is preferred as the primarypackage of many consumer products because plastic film may withstand therigors of a packaging process, given a plastic film's ability to flexand stretch. Also, because plastic film can flex and stretch withouttearing upon the application of force, opening features disposed inplastic packages tend to form clean openings while preserving theintegrity of the rest of the package. In addition, plastic films canalso protect consumer products from moisture and other contaminantsduring shipping and prior to use.

Consumer demand for products and packaging made at least partially fromrenewable and/or recycled resources has increased significantly over thepast decade, and has become a driver of innovation for new and improvedconsumer products and packaging materials. In the context of plasticfilm-based packaging, one way to address this consumer demand is toreplace at least a proportion of new petrol-based plastic material withplastic waste material, also known as recycled plastic material.

Adding recycled materials into the film manufacturing process, however,often negatively impacts the quality of the resulting flexible plasticfilm. Negative impacts on quality can manifest in a number of propertiesof the film, such as diminished mechanical properties (e.g., tensilestrength or elongation at break), undesirable visual and tactileproperties of the film material (e.g., dark spots, gels, etc.),contamination with foreign matter and/or trace chemicals, and/or reducedprocessability such as printing or sealing. Due to these problems,plastic film packages often comprise only relatively small amounts ofrecycled materials, and still exhibit resulting negative properties,such as visual defects and contamination with foreign matter and tracechemicals. As such, plastic films and packages formed from plastic filmsshould be improved.

SUMMARY

Aspects of the present disclosure solve the problems discussed above byapplying features of a high custody recycled material sourcing method toproduce polyolefin films, and packages comprising such polyolefin films,comprising a significant amount (e.g., 10% to 95%, 25% to 95%, 30% to95%, 40% to 95%, 50% to 95%) of recycled polyolefin and havingacceptable mechanical, visual, tactile, and/or chemical properties. Thehigh custody recycled material sourcing method includes storingpost-consumer and/or post-industrial polyolefin material in controlledenvironments (e.g., humidity controlled environments, protectivecovers), removing impurities (e.g., metals, pallet labels, adhesivetapes), and applying traceability procedures (e.g., applying uniqueidentifiers to discrete lots of recycled material). By following thehigh custody recycled material sourcing method, polyolefin films andpackages comprising the same can incorporate a significant amount ofrecycled polyolefin content while not affecting the mechanical, visual,tactile, and/or chemical properties of the finished polyolefin film orpackage comprising such polyolefin film. Furthermore, the recycled filmswith high custody recycled material may be printable without visualdefects, which are not consumer desired. In essence, the high custodysourcing method allows a significant amount of recycled polyolefincontent to be incorporated while still producing a high quality filmthat is at parity, or almost at parity, to virgin polyolefin films. Suchpolyolefin films and packages comprising such polyolefin films with highrecycled resin polyolefin content are consumer desirable while notnegatively affecting the appearance or properties of the plastic filmand packages comprising such films.

DETAILED DESCRIPTION

Various non-limiting forms of the present disclosure will now bedescribed to provide an overall understanding of the principles of thestructure, function, manufacture, and use of the polyolefin filmscontaining recycled polyolefin material disclosed herein. One or moreexamples of these non-limiting forms are illustrated in the accompanyingdrawings. Those of ordinary skill in the art will understand that thepolyolefin films containing recycled polyolefin material describedherein and illustrated in the accompanying drawings are non-limitingexample forms. The features illustrated or described in connection withone non-limiting form may be combined with the features of othernon-limiting forms. Such modifications and variations are intended to beincluded within the scope of the present disclosure.

As used herein, “gel” and “gels” refer to any small defect that distortsa film product. Gels may originate from a variety of different sources,including oxidized polymeric materials, crosslinked polymeric materials,highly-entangled polymeric material, solid and/or unmelted resin, andcontaminants (such as metal, dirt, wood, or other fragments).

As used herein, “virgin polyolefin material” refers to polyolefinmaterial produced directly from the petrochemical or plant-basedfeedstock, such as natural gas or crude oil or sugar cane, and which hasnever been used or processed before.

As used herein, “recycled polyolefin” and “recycled polyolefin material”refer to polyolefin material produced directly from materials other thanpetrochemical or plant-based feedstock, such as polyolefin materialpreviously formed into films, containers, or other goods.

As used herein, “polyolefin resin” refers to polyolefin material in anyform other than the form of a polyolefin film of the present disclosure,including pellets, molten form, precursor scrap film, and the like.“Polyolefin resin” may be in many different forms, including “recycledpolyolefin resin,” “post-industrial polyolefin resin,” and“post-consumer polyolefin resin.”

As used herein, “film” means a sheet structure having a length, width,and thickness (caliper), wherein each of the length and width greatlyexceed the thickness, i.e., by a factor of 1,000 or more, the structurehaving one layer (monolayer) or more respectively adjacent layers(multilayer), each layer being a substantially continuous structureformed of one or more thermoplastic polymer resins (including blendsthereof).

As used herein, “high density polyethylene” (HDPE) means a type ofpolyethylene defined by a density equal to or greater than 0.941 g/cm³.

As used herein, “low density polyethylene” (LDPE) means a type ofpolyethylene defined by a density equal to or less than 0.925 g/cm³.

As used herein, “medium density polyethylene” (MDPE) means a type ofpolyethylene defined by a density range of 0.926-0.940 g/cm³.

As used herein, “linear low density polyethylene” (LLDPE) means a typeof Low Density Polyethylene characterized by substantially linearpolyethylene, with significant numbers of short branches, commonly madeby copolymerization of ethylene with longer-chain olefins. Linearlow-density polyethylene differs structurally from conventionallow-density polyethylene (LDPE) because of the absence of long chainbranching. The linearity of LLDPE results from the differentmanufacturing processes of LLDPE and LDPE. In general, LLDPE is producedat lower temperatures and pressures by copolymerization of ethylene andsuch higher alpha-olefins as butene, hexene, or octene. Thecopolymerization process produces a LLDPE polymer that has a narrowermolecular weight distribution than conventional LDPE and in combinationwith the linear structure, significantly different rheologicalproperties.

An example is two plastic containers (i.e.,primary packaging) of deodorant packaged together with a polyolefin film(i.e., secondary packaging) at least partially or fully wrapped aroundthe two deodorant containers. Another example is a package of shavingblades in cardboard package (i.e., primary packaging) and then enclosedin a polyolefin film shipping package (i.e., secondary packaging).

Polyolefin Films

The present disclosure relates, in part, to polyolefin films comprisinga significant amount of recycled polyolefin material and havingacceptable mechanical, visual, tactile, and/or chemical properties, andpackages comprising such polyolefin films. The polyolefin films of thepresent disclosure may comprise greater than 10%, greater than 20%,greater than 25%, greater than 30%, greater than 40%, greater than 50%,between about 10% and about 95%, between about 25% and about 95%,between about 30% and about 95%, between about 40% and about 95%,between about 45% and about 95%, or between about 50% and about 95%, byweight of the polyolefin film, of recycled polyolefin, specificallyreciting every 1% increment within these ranges and all ranges formedtherein or thereby.

The inclusion of recycled polyolefin materials in a polyolefin film,however, can negatively impact the quality of the resulting polyolefinfilm. Negative impacts on quality can manifest in a number of propertiesof the film, such as diminished mechanical properties (e.g., tensilestrength or elongation at break), undesirable visual and tactileproperties of the film material (e.g., dark spots, gels, etc.),contamination with foreign matter (e.g., wood, metal, trace chemicals),and/or reduced processability such as printing or sealing. Thepolyolefin films of the present disclosure may have acceptablemechanical, visual, tactile, and/or chemical properties.

One property associated with films comprising recycled material is theformation or presence of holes. A hole may comprise a visuallydiscernible area of film where the absence film mass is apparent. Holesare not consumer or manufacturer desired in that products may not besealed off from an external environment. Without wishing to be bound bytheory, it is believed that contaminants brought in with recycledmaterial and/or improper incorporation of recycled material into anewly-formed film may result numerous holes. The polyolefin films of thepresent disclosure, due to the high-custody recycled material sourcingmethod, may have an Average Hole Count between about 0.0 and about 10.0,or between about 0.0 and about 8.0, or between about 0.0 and about 5.0,or between about 0.0 and about 3.0, specifically reciting every 0.1increment within these ranges and all ranges formed therein or thereby,according to the Gel Count Test Method disclosed herein. The polyolefinfilms of the present disclosure may be devoid of holes.

Another property associated with films comprising recycled material isthe presence of gels. Without wishing to be bound by theory, it isbelieved that incorporation of increasing amounts of recycled materialinto a film may result in the formation of an increased number of gelsin a finished film. Gels are not desired because they may distortprinting of the films and/or appear to consumers as a defect. Byemploying the high-custody recycled polyolefin material sourcingmethods, the polyolefin films of the present disclosure may have anAverage Gel Count between about 0.0 and about 100.0, between about 0.0and about 50.0, between about 0.0 and about 25.0, or between about 0.0and about 5.0, specifically reciting every 0.1 increment within theseranges and all ranges formed therein or thereby, according to the GelCount Test Method disclosed herein. The polyolefin films of the presentdisclosure may be devoid of gels.

It is also believed that the incorporation of increasing amounts ofrecycled material into a film may result in the formation of larger gelsand/or gels that more prominently stand off from the surface of thefilm. These type of gels are not desired because they may distortprinting of the films and/or appear to consumers as a defect. Thepolyolefin films of the present disclosure, because of the high-custodyrecycled polyolefin material sourcing method, may have an Average GelHeight of less than 150 mm, less than 90 mm, less than 60 mm, less than45 mm, less than 30 mm, about 0.00 mm to about 150.00 mm, or of about0.00 to about 90.00 mm, or of about 0.00 mm to about 60.00 mm, or ofabout 0.00 mm to about 45.00 mm, or of about 0.00 mm to about 30.00 mm,specifically reciting every 0.01 mm increment within these ranges andall ranges formed therein or thereby, according to the Gel Count TestMethod disclosed herein. Alternatively, or in addition, the polyolefinfilms of the present disclosure may have an Average Relative Gel Heightbetween about 0.0% and about 150.0%, between about 0.0% and about125.0%, between about 0.0% and about 100.0%, between about 0.0% andabout 75.0%, or between about 0.0% and about 50.0%, specificallyreciting every 0.1% increment within these ranges and all ranges formedtherein or thereby, according to the Gel Count Test Method disclosedherein.

Another property associated with films comprising recycled material isthe presence of dark spots in the films or on the surface of the films.Dark spots are not desired because they may distort printing of thefilms or appear to consumers as a defect. Without wishing to be bound bytheory, it is believed that the occurrence of dark spots may increasewith an increasing amount of recycled material incorporated into a filmdue, at least in part, to increased contamination—especiallycarbon-containing contaminants—from the recycled material and/orrecycled material receiving additional heat and processing steps. Thepolyolefin films of the present disclosure, employing the high-custodyrecycled polyolefin material sourcing method, may have a Total SpotCount between about 0.0 and about 100.0, between about 0.0 and about50.0, between about 0.0 and about 25.0, or between about 0.0 and about5.0, specifically reciting every 0.1 increment within these ranges andall ranges formed therein or thereby, according to the Gel Count TestMethod disclosed herein. The polyolefin films of the present disclosuremay be devoid of dark spots.

Additionally, or alternatively, dark spots may be measured on only oneside of the film. The inventors have unexpectedly found the polyolefinfilms of the present disclosure may comprise consumer preferred lowlevels of dark spots on either and/or both sides of the polyolefin film.Without wishing to be bound by theory, the side comprising printedgraphics may have a low level of dark spots and may result in consumerpreferred printing quality. In addition, or alternatively, a side devoidof printed graphics may have a low level of dark spots for consumerpreferred inside visual appearance. The side of the polyolefin filmcontacting the consumer product that may be contained by the film mayhave a low level of dark spots alleviating the consumers perception of avisual contaminant on or in the polyolefin film potentially being incontact with the consumer product. Individual sided analysis of thepolyolefin films of the present disclosure may be important where, forexample, one side of a film is coated with an ink, renderingvisualization of dark spots difficult.

Recycled polyolefin content of a polyolefin film may be determined usingvisual inspection. Manufacturers may advertise the use of recycledmaterials, and may also specify the percentage of recycled material. Forexample, visual inspection of a package comprising a polyolefin film maybe used to identify logos or other indicia indicating the content and/orlevel of recycled polyolefin material. Additionally, or alternatively,visual inspection may include the use of a light box or microscopy toidentify one or more of the common indicators of recycled content inpolyolefin films, such as holes in the film, gels, and dark spots.

Due at least in part to the high-custody recycled polyolefin materialsourcing method, the polyolefin films of the present disclosure maycomprise significantly lower levels of certain trace chemicals ascompared to traditional polyolefin films containing recycled materials.Without wishing to be bound by theory, it is believed that the inclusionof increasing amounts of recycled materials, which may have been exposedto environmental and/or other contaminants before being introduced intothe polyolefin film manufacturing process, into a polyolefin film mayresult in increased levels of certain trace chemicals. Low levels oftrace chemicals are consumer preferred.

Recycled polyolefin may be categorized into several different classes.One class of recycled polyolefin may be “post-industrial polyolefinmaterial” (also known as “PIPM”, “post-industrial resin”, or “PIR”).Post-industrial polyolefin material (PIPM) is waste and/or scrapgenerated in a manufacturing process that may be added back into theoriginal manufacturing process. For example, the process ofmanufacturing a package comprising a polyolefin film may comprise a stepof forming the polyolefin film, wherein waste and/or scrap polyolefinmaterial is produced. When this waste and/or scrap polyolefin materialis recycled into the polyolefin film forming step of the manufacturingprocess, such waste and/or scrap polyolefin material may be termed PIPM.Additionally, waste and/or scrap polyolefin film portions of a finishedpackage (such as a removed wicket panel) that is recycled into thepolyolefin film forming step of the manufacturing process may also betermed PIPM, so long as the process forms a closed loop, being addedback to the original manufacturing process. PIPM may be less prone toacquire contaminants because the PIPM material remains in a closed loopsystem, being recycled back into the original film manufacturingprocess. The polyolefin films of the present disclosure may comprisepost-industrial polyolefin material as the recycled polyolefin. Thepolyolefin films of the present disclosure may comprise post-industrialpolyolefin material as the recycled polyolefin. The polyolefin films ofthe present disclosure may comprise post-industrial polyolefin materialas the recycled polyolefin, wherein the recycle polyolefin comprisespolyethylenes (including LLDPE, LDPE, MDPE, and/or HDPE),polypropylene-ethylene interpolymer and copolymers having at least oneolefinic constituent, and any mixtures thereof.

Another class of material may be “post-consumer polyolefin material”(also known as “PCPM”, “post-consumer resin”, or “PCR”). Post-consumerpolyolefin material (PCPM) is polyolefin material that has beenpreviously formed into an intermediate or final product form and isoutside of the original manufacturing process as described aboverelative to the post-industrial polyolefin material. PCPM may be in theform of, for example, intermediate packaging material and/or finishedpackaging material. PCPM may be used or unused, meaning that thepolyolefin material may, or may not, have been in contact with aconsumer product, product, or packaged good, or otherwise utilized forits intended purpose. PCPM material may be diverted from landfillsand/or collected from, for example, distribution centers, supermarkets,packaging material manufacturers, film and/or polyolefin resinmanufacturers, food-producing plants, consumer product-producing plants,agricultural operations, and the like. PCPM may be utilized in theproduction of other commodities, including other polyolefin-containingcommodities.

The polyolefin films of the present disclosure may be formed from asingle layer of polyolefin material (including recycled polyolefinmaterial)—a monolayer film, —or may be formed from a laminate of morethan one layer of polyolefin material—a multilayer film. A multilayerfilm may have, for example, a first skin layer formed of a first polymerand a second skin layer formed of a second polymer. Either of the skinlayers may contain recycled polyolefin material. The first polymer andthe second polymer may be the same, or may be different.

A multilayer film may have layers of polyolefin compositionsparticularly chosen for the characteristics they impart to the film. Forexample, one or two skin layers may be formed of compositions chosenfor, e.g., surface gloss; printability; smooth feel; pliability; lownoise generation (upon being handled and manipulated, as by a consumer);relatively lower melt temperature and fusibility/weldability; low oxygenpermeability; low moisture permeability; or any combination of thesecharacteristics. One or more intermediate layers may be formed ofcompositions chosen for, e.g., tensile strength; stiffness; toughness;suitability for inclusion of blended-in recycled material;environmentally-friendly and/or sustainable material sourceability;relatively higher melt temperature; co-extrusion compatibility withadjacent layers (such that strong bonding between layers occurs uponco-extrusion); or any combination of these characteristics.

Each of the layers may include a base polyolefin. Base polyolefins mayinclude polyethylenes (including LLDPE, LDPE, MDPE, and/or HDPE),polypropylenes, polybutadienes, polypropylene-ethylene interpolymer andcopolymers having at least one olefinic constituent, and any mixturesthereof.

Referring to FIGS. 4 and 5 , the polyolefin films of the presentdisclosure may be formed from two or more layers of polyolefin material.As shown in FIG. 4 , the polyolefin film 400 comprises a first filmlayer 406 and a second film layer 408. The first film layer 406 may formthe first surface 402 of the polyolefin film 400. The second film layer408 may form the second surface 404 of the polyolefin film 400. As shownin FIG. 5 , the polyolefin film 500 may have an intermediate film layer505 disposed between a first film layer 506 and a second layer 508. Thefirst film layer 506 may form the first surface 502, and the second filmlayer 508 may form the second surface 504.

The different layers of the multilayer films of the present disclosuremay differ in thickness (caliper). Referring to FIG. 5 , theintermediate film layer 505 may have a greater thickness than the firstfilm layer 506 and/or the second film layer 508. The thickness of thefirst film layer 506 and/or the second film layer 508 may beapproximately one-half the thickness of the intermediate film layer 505.In a form, the thicknesses of the different layers of the multilayerfilms may be in a ratio of 1:2:1 (first film layer:intermediate filmlayer:second film layer). In another form, the thicknesses of thedifferent layers of the multilayer films may be in a ratio of 0.5:2:0.5(first film layer:intermediate film layer:second film layer). In yetanother form, the thicknesses of the different layers of the multilayerfilms may be in a ratio of 0.5:2:1 (first film layer:intermediate filmlayer:second film layer).

The individual layers of the multilayer films of the present disclosuremay comprise the same polyolefin material, or may comprise differentpolyolefin materials. Referring again to FIG. 4 , the first film layer406 may comprise recycled polyolefin material, whereas the second filmlayer 408 may be devoid of (free of) recycled polyolefin material. Inanother form, the first film layer 406 may be devoid of recycledpolyolefin material, whereas the second film layer 408 may compriserecycled polyolefin material. In yet another form, the first film layer406 and the second film layer 408 may comprise recycled polyolefinmaterial at different levels or the same levels. Referring to FIG. 5 ,the intermediate film layer 505 may comprise recycled polyolefinmaterial, whereas the first film layer 506 and the second film layer 508may be devoid of recycled polyolefin material. In another form, theintermediate film layer 505 may be devoid of recycled polyolefinmaterial, whereas the first film layer 506 and/or the second film layer508 may comprise recycled polyolefin material. In yet another form, thefirst film layer 506, the second film layer 508, and the intermediatefilm layer 505 may each comprise the same, or different, amounts ofrecycled polyolefin material. As discussed herein, the first film layer506 and the second film layer 508, i.e., the outer-most layers of thepolyolefin film, may be formed of compositions chosen for theirfunctional characteristics, such as gloss, printability, lowpermeability, etc. The outer-most layers, or at least one of theouter-most layers of the polyolefin film may also be formed of onlyvirgin polyolefin material in order to provide a barrier between a layerof the film comprising recycled polyolefin material and a consumerproduct.

A multilayer film as contemplated herein may comprise one or more tielayers disposed between other layers. A tie layer may be necessary whenthe polymers of adjoining layers would not otherwise be miscible orcompatible so as to bond to each other during extrusion. For example, atie layer between a polyethylene skin layer and an intermediate layerhaving a large polylactic acid content may be deemed desirable. Thus,for example, in a multilayer film having three main layers—two skinlayers and an intermediate layer disposed between them, tie layers maybe disposed between the intermediate layer and each of the skin layers.A tie layer may include one or more functionalized polyolefins. In someexample, a tie layer may include from 5%, 10%, 20%, 30%, 40% or 45% to55%, 60%, 70%, 80%, 90%, or 100%, by weight of the tie layer, of the oneor more functionalized polyolefins. A tie layer may consist essentiallyof the one or more functionalized polyolefins.

The tie layer may comprise a functionalized polyolefin that possesses apolar component provided by one or more functional groups that iscompatible with the materials of the intermediate layer(s) and anon-polar component provided by an olefin that is compatible with one ormore polyolefins of the adjacent skin layer. The polar component may,for example, be provided by one or more functional groups and thenon-polar component may be provided by an olefin. The olefin componentmay generally be formed from any linear or branched α-olefin monomer,oligomer, or polymer (including copolymers) derived from an olefinmonomer. The α-olefin monomer typically has from 2 to 14 carbon atomsand preferably from 2 to 6 carbon atoms. Examples of suitable monomersinclude, but not limited to, ethylene, propylene, butene, pentene,hexene, 2-methyl-1-propene, 3-methyl-1-pentene, 4-methyl-1-pentene, and5-methyl-1-hexene. Examples of polyolefins include both homopolymers andcopolymers, i.e., polyethylene, ethylene copolymers such as EPDM,polypropylene, propylene copolymers, and polymethylpentene polymers.

An olefin copolymer can include a minor amount of non-olefinic monomers,such as styrene, vinyl acetate, diene, or acrylic and non-acrylicmonomer. Functional groups may be incorporated into the polymer backboneusing a variety of known techniques. For example, a monomer containingthe functional group may be grafted onto a polyolefin backbone to form agraft copolymer. Such grafting techniques are well known in the art anddescribed, for instance, in U.S. Pat. No. 5,179,164. In otherembodiments, the monomer containing the functional groups may becopolymerized with an olefin monomer to form a block or randomcopolymer. Regardless of the manner in which it is incorporated, thefunctional group of the compatibilizer may be any group that provides apolar segment to the molecule, such as a carboxyl group, acid anhydridegroup, acid amide group, imide group, carboxylate group, epoxy group,amino group, isocyanate group, group having oxazoline ring, hydroxylgroup, and so forth. Maleic anhydride modified polyolefins areparticularly suitable for use in the present invention. Such modifiedpolyolefins are typically formed by grafting maleic anhydride onto apolymeric backbone material. Such maleated polyolefins are availablefrom E. I. du Pont de Nemours and Company under the designationFusabond, such as the P Series (chemically modified polypropylene), ESeries (chemically modified polyethylene), C Series (chemically modifiedethylene vinyl acetate), A Series (chemically modified ethylene acrylatecopolymers or terpolymers), or N Series (chemically modifiedethylene-propylene, ethylene-propylene diene monomer (“EPDM”) orethylene-octene). Alternatively, maleated polyolefins are also availablefrom Chemtura Corp. under the designation POLYBOND and Eastman ChemicalCompany under the designation Eastman G SERIES, and AMPLIFY™ GRFunctional Polymers (maleic anhydride grafted polyolefins). Otherexamples include LOTADER AX8900 (polyethylene-methyl acrylate-glycidylmethacrylate terpolymer) and LOTADER TX 8030 (polyethylene-acrylicester-maleic anhydride terpolymer) available from Arkema, Columbes,France.

In some aspects, the tie layer can be a resin composition as disclosedin U.S. Pat. No. 8,114,522. This resin composition includes a modifiedPO resin and a terpene resin. Alternatively, it includes a polylacticacid resin, a modified polyolefin resin, and a hydrogenated petroleumresin. These compositions are suitable for use as a tie layer betweenthe outer layer and the core layer.

In some examples, an outer layer and tie layer may be essentiallycombined as an outer layer by incorporating a functionalized polyolefininto one or both of the outer layers. In these instances, themulti-layer film may comprise 3 or 4 layers. In the case of a 3 layerfilm, the film may comprise a first outer layer comprising a polyolefinand/or a functionalized polyolefin, one or more core layers, and asecond outer layer comprising a polyolefin and/or a functionalizedpolyolefin). In the case of a 4 layer film, the film may comprise afirst outer layer comprising a polyolefin and/or a functionalizedpolyolefin, one or more core layers, a tie layer, and a second outerlayer comprising a polyolefin.

Multilayer polyolefin films of the present disclosure may be formed byany process known in the art, including co-extrusion and lamination.Where multilayer polyolefin films are formed by lamination, an adhesivemay be applied, for example by printing, to one or multiple surfaces offilm layers that are subsequently brought into contact with each otherand joined.

Any of the layers of the multilayer film may comprise small amounts ofone or more additives. Typically, the additives may comprise less thanabout 15%, 10%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, 0.01%, or between about0.01% and about 15%, between about 0.1% and about 10%, or between about0.5% and about 10% by weight of the layer of the additive.

Packages

The polyolefin films of the present disclosure may form at least aportion of a package. The package may comprise the polyolefin films ofthe present disclosure, may be formed from the polyolefin films of thepresent disclosure, or may be formed entirely from the polyolefin filmsof the present disclosure.

The packages may take any shape and size and be suitable for a consumerproduct to be contained therein or partially therein. For example, thepackage may comprise a plurality of panels which define an interiorcompartment and at least partially enclose one or more than one consumerproduct. The packages of the present disclosure may be formed from asingle sheet of polyolefin film of the present disclosure suitablyfolded to form a bag structure, as shown in FIG. 6 . A bag structure 600may be formed from a single sheet of polyolefin film that is suitablyfolded to form bag gussets 601, 602 and then joined along portions bybonding to form two side seams 603, 604 on opposite sides, to form bagstructure 600 with no seam on a first package surface 605, and open atthe other end (e.g., a gusseted bag structure). Thereafter, the bagstructure may be filled by inserting the consumer product through theopen end. The open end opposite package surface 606 may then be closedby suitably folding to form closing gussets 607 and another closinggusset, bringing the polyolefin film edges together, and bonding themtogether to form end seam 609 and second package surface 610.

Referring to FIG. 7 , the packages 600′ may include an opening feature700 along a top or bottom edge portion of the package for opening thepackage 600′. The opening feature 700 may, for example, be a perforationor line of perforations 701. The opening feature 700 may be reclosable.The reclosable features may include a lid, tape tab fastener, hook andloop fastener, snap, button, or latch, for example. The package 600′ mayalso comprise a handle 702 for ease of carrying. Package surface 606′ isillustrated. Second package surface 610′ is illustrated.

Other package shapes are contemplated, including flow wrap or horizontalform fill-and-seal wrap comprising polyolefin films of the presentdisclosure. Referring to FIG. 8 , a flow wrap package 800 may comprise afirst surface 801 and an opposing second surface 802. Rounded edges maybe provided as a transition between the first surface 801 and the secondsurface 802. One or more fold lines may be provided between the firstsurface 801 and the second surface 802. The flow wrap package 800 mayfurther comprise end seals 803 and 804, and a hoop seam 805 which may bedisposed on the second surface 802. Flow wrap packages may be useful,particularly where a low number of products are included within apackage.

Bonds forming any or all of the package seals, such as seams, may becreated by welding. (Herein, “weld” refers to a union between separateportions of polyolefin film, effected by application of direct orindirect (e.g., ultrasonic) heating energy and pressure that causesseparate portions of the film to at least partially melt and fusetogether to some extent, forming a bonded area, joint, or seam whichcannot be separated without substantial destruction to the remainder ofone or both joined portions.) If package-forming machinery forms weldsin the polyolefin film that join the film stock to itself by applyingheating energy that causes the film to fuse to itself, it may bedesirable that the film stock be multilayer film, and that the layer(s)to be brought into contact and fused be formed of polymer(s) that havelower melting temperature(s) than those of the polymer(s) used to formthe other layer(s). This enables heating energy to be applied to adegree sufficient to heat the layer(s) in contact and cause them tofuse, but not sufficient to cause undesired melting and deformation ofthe other layer(s), which could cause the package to be misshapen and/ordisplace and/or distort printing on the film stock.

The packages of the present disclosure may comprise a polyolefin film ofthe present disclosure and a consumer product. As shown in FIG. 9 , thepackages 1000 may define an interior compartment 1002 such that thepolyolefin film may at least partially enclose one or more than oneconsumer product 1004. The polyolefin film may be disposed around andfully enclose the consumer product. The consumer product may be disposedwithin the polyolefin film. In a form, the packages of the presentdisclosure consist of the polyolefin films of the present disclosure.

Referring again to FIG. 1 , the polyolefin film 100 of the package maybe oriented such that the first surface 102 faces away from the consumerproduct, and the second surface 104 faces toward the consumer product.In such a form, the first surface may be considered the outer surface ofthe polyolefin film and/or package, and the second surface may beconsidered the inner surface of the polyolefin film and/or package. Inanother form, the first surface 102 may face toward the consumerproduct, and the second surface 104 may face away from the consumerproduct. In such a form, the second surface may be considered the outersurface of the polyolefin film and/or package, and the first surface maybe considered the inner surface of the polyolefin film and/or package.The specific orientation of the polyolefin film may be beneficial, forexample, when only one surface of the polyolefin film comprises printedgraphics. In certain package configurations, it may be desirable to haveprinted graphics only on the outer surface of the polyolefin film facingaway from the consumer product. This configuration may be beneficialbecause it may reduce or prevent ink, or other materials used inprinting graphics, from rubbing off on the consumer product in thepackage.

The specific orientation of the polyolefin films relative to theconsumer product may be relevant to multilayer polyolefin films as well.Referring to FIGS. 4 and 5 , the first surfaces 402/502 may be orientedfacing away or toward the consumer product. The second surfaces 404/504may be oriented facing away or toward the consumer product. Asdiscussed, multilayer polyolefin films may exhibit sidedness because thedifferent layers of the multilayer polyolefin films may providedifferent characteristics or functionalities. It may therefore bebeneficial that the first and/or second surface face away from theconsumer product. For example, the first layer of a multilayerpolyolefin film may form the first surface of the film, and the firstlayer may have been selected because it readily receives and retainsprinted graphics. As such, it may be desirable that the first surfaceface away from the consumer product and toward the consumer. In anotherexample, it may be desirable that the second polyolefin layer 408/508forms the second surface 404/504 that faces the consumer product, andthat the second polyolefin layer 408/508 is free of recycled polyolefinmaterial. It may be desirable that the consumer product only come incontact with a portion of the polyolefin film that comprises virginpolyolefin material, or is otherwise free of recycled polyolefinmaterial.

As shown in Table 3, polyolefin film comprising PCPM sourced from ahigh-custody sourcing method produces a film with significantly fewergels, gels with a smaller profile, and significantly fewer dark spots. Afilm with fewer and lower-profile gels is less likely to encounterissues during printing, as gels may impair the printing process and maydistort graphics printed on the film surface.

Gel Count Test Method

The Gel Count Test Method is used to quantify the incidence of defectsof interest in sample packaging film of interest. Evaluation on severalspecimens of a sample packaging film is primarily done visually, andseveral output parameters relating to gels, dark spots, and holes areestablished.

Five like specimens, rectangular and 20 cm×20 cm, are taken from asample packaging film of interest. If the film is available as rollstock, the five specimens are cut from one or more rolls of material,with material preferentially being taken from unprinted regions. If thepackaging film of interest is not available in roll stock form and is,for example, only available as formed packaging bags for containingconsumer products, these five specimens are extracted from one or morepackaging bags. The surface of the film facing inward in the bag (i.e.,toward and generally enveloping consumer products when the bag is loadedwith product) is defined as the inner surface of the film and thesurface of the film facing outward away from consumer products isdefined as the outer surface of the film. In the case the specimens aretaken from roll stock before bags are formed (and potentially before anyprinted step present in the film conversion process), if the surfaceintended to be an outer surface after conversion is known, this isconsidered to be the outer surface and the opposite surface isconsidered to be the inner surface. If the surface intended to be anouter surface is unknown, the outer surface is determined in thedark-spot-counting procedure as described below.

Each of the five film specimens is backlit by being placed on a whitelight box sequentially and viewed with the naked eye. For each of thefive film specimens, any holes or tears apparent in the film areidentified and marked. A hole may comprise a visually discernible areaof film where the absence film mass is apparent. A tear may comprise ahole which has an elongated opening or absence of film mass extending inone direction. Any gels apparent are also identified and marked. (Forthe purposes of this method, a gel is a distinct individual entity,generally visually discernible and consistent with a small clump ofcross-linked polymer resin or as defined elsewhere within this patentdocument.) A caliper gauge with flat, round foot 6.00 to 6.25 mm indiameter and exerting less than 3.5 N of force is used to measure andrecord the absolute height of each gel to the nearest 0.01 mm. Oneexample of a suitable apparatus is caliper gauge model ID-C112BSavailable from Mitutoyo Corporation, Kawasaki, Japan, or equivalent. Foreach gel, the caliper of proximal, well-formed film is also measured inlike fashion. For each gel, its gel height is defined asgel height [mm]=absolute height of gel [mm]−proximal film caliper [mm]and its relative gel height, in percent, is defined as

${{relative}{gel}{height}\lbrack\%\rbrack} = {\frac{{gel}{{height}\lbrack{mm}\rbrack}}{{proximal}{film}{{caliper}\lbrack{mm}\rbrack}} \times 100{\%.}}$

For each gel, the gel height and relative gel height are measured,calculated, and recorded. If a cluster of gels containing individuallydiscernible gels spaced so closely such that the caliper gauge cannotmeasure the height of each gel individually, the gel height and relativegel height of the tallest gel in the cluster is assigned to all gels inthe cluster.

Each surface of each of the five film specimens is then viewed by thenaked eye front-lit under diffuse white light, and any dark specs orspots are identified and counted. For specimens of sample film for whichthe inner surface and outer surface are not known, the surface with thegreater number of spots is considered the inner surface. For specimensof sample film for which the inner surface and outer surface is known,the number of dark specs or spots are counted as appearing on the innersurface or the outer surface depending which is being viewed.

For the sample film evaluated via the five specimens, the Average HoleCount is defined as the total number of holes observed among the fivespecimens divided by five and is reported to the nearest tenth. TheAverage Gel Count is defined as the total number of gels observed amongthe five specimens divided by five and reported to the nearest tenth.The Average Gel Height is the arithmetic mean among all gel heightsrecorded, reported to the nearest 0.002 mm. The Average Relative GelHeight is the arithmetic mean among all relative gel heights recordedand is reported to the nearest 0.1%. The Average Inner-Surface SpotCount is the total number of dark specs or spots observed on the innersurface of the five specimens divided by five and reported to thenearest tenth. The Average Outer-Surface Spot Count is the total numberof dark specs or spots observed on the outer surface of the fivespecimens divided by five and reported to the nearest tenth. The AverageTotal Spot Count is the sum of the Average Inner-Surface Spot Count andthe Average Outer-Surface Spot Count and is reported to the nearesttenth.

Trace Chemicals Test Method

The content on a mass per mass basis of trace chemicals present inpackaging film or recycled polyolefin material is determined usingmethods containing sample extraction and instrumental analysisapproaches known of those of skill in the art and understood to becapable of extracting and detecting essentially all of a particulartrace chemical in packaging film. Suitable overall method specifics varybased on the particular trace chemical being quantified, though a commonoverall method structure is generally followed. A suitable methodgenerally begins with increasing the surface area of a representativepackaging film or recycled polyolefin material sample by cutting,shredding, and/or milling into small particles. An extraction step isthen performed using a solvent capable of dissolving or diffusing intothe polymer sample and in which the trace chemical is readily soluble.The extraction process conditions (e.g., time and temperature) areoptimized to maximize trace chemical recovery and common approachesinclude but are not limited to Soxhlet extraction, accelerated solventextraction, and/or ultrasonic extraction. Internal standards (usuallystable-isotope-labeled versions of the trace chemicals if massspectrometry-based detection approaches are used) are added during theextraction step to account for potential losses during extraction andsubsequent processing steps. After extraction is complete, theextraction solvent is isolated and worked up for instrumental analysis.Depending on the solvent used for extraction, the required quantitationlimit, and the specific instrumental approach used, generation of aspecimen suitable for instrumental analysis may require multiple cleanupand/or concentration steps including but not limited tocentrifugation/filtration, liquid/liquid extraction, and/or columnchromatography. The trace chemical in the worked-up specimen is thenquantified using instrumental methods (e.g., GC-MS, GC-MS/MS, GC-HRMS,LC-MS/MS, etc.) known to those of skill in the art and specificallyadapted to the trace chemical of interest. Suitable instrumentalapproaches may be developed de novo or may be based on standard, knownmethods for particular trace chemicals (e.g., US EPA Method 1613 in thecase of dioxins and furans or US EPA 1668 for PCBs). Based on acombination of raw instrumental quantitative results, extraction solventworkup steps, original extraction volume, and starting specimen mass,the mass content of a trace chemical per mass of starting specimenmaterial is calculated and is reported as the level of the tracechemical in the packaging film tested. Given the generally low levels oftrace chemicals present, common units used in reported levels of tracechemicals are μg/kg and ng/kg (equivalent to the ppb and ppt levels,respectively).

One of skill in the art will recognize that trace chemicals are oftenpresent at very low “trace” levels, meaning that under somecircumstances, environmental and/or laboratory background levels ofthese same trace chemicals may give rise to false positive detects orfalsely elevated results if appropriate precautions are not taken. Whileone of skill in the art recognizes that a suite of measures may beneeded to minimize such false results, one obligatory measure is toinclude a true “blank” beginning with solvent carried in parallelthrough the extraction step, extraction solvent workup, and instrumentalanalysis.

Using the suitable overall methodology outlined above, one of skill inthe art may quantify a range of trace chemicals potentially present in apackaging film or recycled polyolefin material sample of interest. Forexample, the level of isononylphenol (CAS RN 11066-49-2) may bedetermined and reported as mass of trace chemical per mass of packagingfilm or recycled polyolefin material in units of μg/kg. Similarly, thelevel of PCB 77 (CAS RN 32598-13-3) may be determined and reported inunits of ng/kg, the level of PCB 118 (CAS RN 31508-00-6) may bedetermined and reported in units of ng/kg, the level of OCDD (CAS RN3268-87-9), a dioxin, may be determined and reported in units of ng/kg,the level of OCDF (CAS RN 39001-02-0), a furan, may be determined andreported in units of ng/kg, the level of bisphenol A (CAS RN 80-05-7),also known as BPA, may be determined and reported in units of μg/kg, andthe level of diisononyl phthalate (CAN RN 28553-12-0), also known asDINP, may be determined and reported in units of μg/kg.

In-Bag Stack Height Test

The in-bag stack height of a package of absorbent articles is determinedas follows:

Equipment:

A thickness tester with a flat, rigid horizontal sliding plate is used.The thickness tester is configured so that the horizontal sliding platemoves freely in a vertical direction with the horizontal sliding platealways maintained in a horizontal orientation directly above a flat,rigid horizontal base plate. The thickness tester includes a suitabledevice for measuring the gap between the horizontal sliding plate andthe horizontal base plate to within ±0.5 mm. The horizontal slidingplate and the horizontal base plate are larger than the surface of theabsorbent article package that contacts each plate, i.e., each plateextends past the contact surface of the absorbent article package in alldirections. The horizontal sliding plate exerts a downward force of850±1 gram-force (8.34 N) on the absorbent article package, which may beachieved by placing a suitable weight on the center of thenon-package-contacting top surface of the horizontal sliding plate sothat the total mass of the sliding plate plus added weight is 850±1grams.

Test Procedure:

Absorbent article packages are equilibrated at 23±2° C. and 50±5%relative humidity prior to measurement.

The horizontal sliding plate is raised and an absorbent article packageis placed centrally under the horizontal sliding plate in such a waythat the absorbent articles within the package are in a horizontalorientation (see FIG. 3 ). Any handle or other packaging feature on thesurfaces of the package that would contact either of the plates isfolded flat against the surface of the package so as to minimize theirimpact on the measurement. The horizontal sliding plate is loweredslowly until it contacts the top surface of the package and thenreleased. The gap between the horizontal plates is measured to within±0.5 mm ten seconds after releasing the horizontal sliding plate. Fiveidentical packages (same size packages and same absorbent articlescounts) are measured and the arithmetic mean is reported as the packagewidth. The “In-Bag Stack Height”=(package width/absorbent article countper stack)×10 is calculated and reported to within ±0.5 mm.
